The top plate, the bottom plate, and the support plate are arranged in parallel. The end face of the housing away from the first baffle is farther from the first baffle than the end face of the insert plate away from the first baffle.
[0009] When the second side of the slider is attached to the side of the top plate facing the support plate, the third side is attached to the inner wall of one of the side plates, and the fourth side is attached to the inner wall of the other side plate, the strip groove and the ball of the slider are aligned.
[0010] Optionally, the inner wall surfaces of the two side plates at the ends away from the first baffle gradually move away from each other.
[0011] Optionally, the base plate is provided with a plurality of support columns, one end of the support column is fixedly connected to the base plate, and the other end of the support column is connected to the support plate. When the slider is sleeved on the insert plate, the support column is located in the guide groove area of the slider.
[0012] Optionally, the second baffle has a protrusion on the side opposite to the first baffle. When the second baffle abuts against the slider located inside the housing, the end of the protrusion opposite to the first baffle extends out of the housing.
[0013] Optionally, the bottom plate is provided with a guide groove at the end away from the first baffle. The bottom surface of the guide groove near the first baffle is aligned with the end surface of the insert plate away from the first baffle. The guide groove is used to cooperate with the guide rail that mates with the slider. When the side of the guide rail abuts against the side wall of the guide groove and the end surface of the guide rail abuts against the bottom surface of the guide groove, the guide rail and the guide groove of the slider are aligned.
[0014] The top plate is provided with a strip-shaped through groove, the length direction of which is parallel to the length direction of the first stop bar. The strip-shaped through groove is used by the external structure to push the slider on the guide rail within the outer shell.

[0033] This application provides a guide rail slider ball anti-drop device.
[0034] like Figure 1 and Figure 2 As shown, the ball anti-drop device of this application is applicable to a slider 5 in which a row of balls 55 is provided on each of the two sides inside the slider 5.
[0035] A ball bearing anti-dislodgement device for a guide rail 6 and a slider 5 includes an insert plate 1 for sliding engagement with the inside of the slider 5. The insert plate 1 includes a support plate 11 and a first stop bar 12 and a second stop bar 13 located on opposite sides of the support plate 11. A strip-shaped groove 14 is provided on the opposite sides of the first stop bar 12 and the second stop bar 13. The strip-shaped groove 14 matches the portion of the ball bearing 55 protruding from the inside of the slider 5, and the inner wall of the strip-shaped groove 14 wraps around the portion of the ball bearing 55 protruding from the inside of the slider 5. The length of the insert plate 1 is greater than the length of the slider 5, and the strip-shaped groove 14 is arc-shaped.
[0036] One end of the insert plate 1 is fixedly connected to a first baffle 2, which is used to abut against one end face of the slider 5. The other end of the insert plate 1 is provided with a second baffle 3, which is used to abut against the other end face of the slider 5. The second baffle 3 is provided with a through hole 31 for the end of the insert plate 1 to pass through. The second baffle 3 and the end of the insert plate 1 are engaged.
[0037] When the insert plate 1 is inserted into the slider 5, one end of the slider 5 abuts against the first baffle 2, and then the second baffle 3 is installed on the other end of the insert plate 1. The first baffle 2 and the second baffle 3 restrict the movement of the slider 5 on the insert plate 1. The first baffle 2 and the second baffle 3 keep the slider 5 on the insert plate 1. At the same time, the first baffle 12 and the second baffle 12 cover the balls 55 on both sides inside the slider 5, which can prevent the balls 55 from falling off the slider 5 accidentally during transportation.
[0038] To facilitate understanding of this application, the side surface of the slider 5 is defined as follows: the surface of the slider 5 perpendicular to its sliding direction on the guide rail 6 is the end face; one pair of opposite sides of the slider 5 are the first side surface 51 and the second side surface 52, the first side surface 51 is the side corresponding to the opening of the guide groove of the slider 5, the second side surface 52 is used for fixed connection of external accessories, and the other pair of opposite sides of the slider 5 are the third side surface 53 and the fourth side surface 54.
[0039] like Figure 1 , Figure 3 and Figure 4 As shown, the guide rail 6 slider 5 ball anti-drop device of this application also includes a housing 4. The housing 4 has openings at both ends. The insert plate 1 and the first baffle 2 are located inside the housing 4. The first baffle 2 is fixedly connected to one end of the housing 4. The housing 4 includes a top plate 41, a bottom plate 42, and two side plates 43. The top plate 41, the bottom plate 42, and the support plate 11 are arranged in parallel. The end face of the housing 4 away from the first baffle 2 is farther from the first baffle 2 than the end face of the insert plate 1 away from the first baffle 2. In the embodiments of this application, the housing 4 is an integral structure. The housing 4 and the first baffle 2 are glued together or connected by bolts. The housing 4 and the first baffle 2 can also be integrally set, and the first baffle 2 and the insert plate 1 are an integral structure.
[0040] When the second side 52 of the slider 5 is in contact with the side of the top plate 41 facing the support plate 11, the third side 53 is in contact with the inner wall of one of the side plates 43, and the fourth side 54 is in contact with the inner wall of the other side plate 43, the strip groove 14 and the ball bearing 55 of the slider 5 are aligned.
[0041] When connecting the insert plate 1 and the slider 5, move the slider 5 along its own sliding direction to the end of the outer shell 4 away from the ground baffle, so that the inner wall of the slider 5, the side plate 43 of the outer shell 4, and the top plate 41 of the outer shell 4 are aligned. This ensures that the guide groove of the slider 5 is aligned with the insert plate 1, that is, that the strip groove 14 on the first baffle 12 and the second baffle 13 is aligned with the ball bearings 55 on both sides inside the slider 5. Push the slider 5 into the outer shell 4 and make the slider 5 abut against the first baffle 2. Then, put the second baffle 3 on the insert plate 1 to complete the connection between the slider 5 and the insert plate 1. At the same time, the outer shell 4 can protect the slider 5 and package the slider 5. In this application, the end face of the outer shell 4 that is farther away from the first baffle 2 is farther away from the first baffle 2 than the end face of the insert plate 1 that is farther away from the first baffle 2. That is, when the slider 5 just enters the outer shell 4, the slider 5 has not yet contacted the insert plate 1. That is, before the insert plate 1 and the slider 5 are connected, the position of the slider 5 is first restricted by the outer shell 4. After the outer shell 4 aligns the slider 5 and the insert plate 1, the slider 5 gradually approaches the insert plate 1 and forms a nesting relationship until the end of the insert plate 1 that is farther away from the first baffle 2 passes through the slider 5.
[0042] The inner wall surfaces of the two side plates 43 at the ends away from the first baffle 2 gradually move away from each other. In this embodiment, the inner wall edges of the ends of the two side plates 43 away from the first baffle 2 are chamfered to form a flared structure, which guides the slider 5 as it enters the outer shell 4.
[0043] The base plate 42 is provided with a plurality of support columns 15. One end of each support column 15 is fixedly connected to the base plate 42, and the other end is connected to the support plate 11. When the slider 5 is fitted onto the insert plate 1, the support column 15 is located in the guide groove area of the slider 5. The support column 15 avoids the solid part of the slider 5, ensuring the positional stability of the insert plate 1 relative to the outer shell 4. This ensures that after the slider 5 enters the outer shell 4, the insert plate 1 can accurately align with the guide groove of the slider 5, that is, the strip groove 14 on the first stop bar 12 and the second stop bar 13 aligns with the ball bearing 55 inside the slider 5. In this embodiment, the two ends of the support column 15 are glued together with the base plate 42 and the insert plate 1. In other embodiments, the support column 15, the base plate 42, and the insert plate 1 can also be an integral structure.
[0044] The second baffle 3 has a protrusion 33 on the side opposite to the first baffle 2. When the second baffle 3 abuts against the slider 5 located inside the outer shell 4, the end of the protrusion 33 opposite to the first baffle extends out of the outer shell 4. The protrusion 33 facilitates pulling the second baffle 3 out of the outer shell 4 and pushing the second baffle 3 into the outer shell 4. In this application, the protrusion 33 is a round rod. In this embodiment, the side of the second baffle 3 corresponding to the top plate 41 and the side plate 43 matches the inner wall of the outer shell 4. When installing the second baffle 3, when the second baffle 3 is attached to the top plate 41 and the side plate 43 of the outer shell 4, the through hole 31 and the insert plate 1 are aligned, which can realize the quick installation of the second baffle 3. The protrusion 33 and the second baffle 3 are an integral structure.
[0045] The specific method for the end engagement of the second baffle 3 and the insert plate 1 in this application can be as follows: A protrusion is provided at the end of the support plate 11 away from the first baffle 2. The protrusion is located on the side of the support plate 11 facing the opening of the guide groove of the slider 5, and the protrusion is located in the area of the support plate 11 corresponding to the opening of the guide groove of the slider 5. A protrusion 32 is provided on the inner wall of the through hole 31 near the opening of the slider 5. The protrusion is used to abut against the side of the protrusion 32 facing away from the first baffle 2. The second baffle 3 is first fitted onto the outer periphery of the insert plate 1. Pushing the second baffle 3 closer to the first baffle 2 causes the protrusion 32 to pass over the protrusion, thereby causing the ends of the second baffle 3 and the insert plate 1 to engage. In other embodiments, protruding structures are provided on both sides of the through hole 31. After the second baffle 3 is sleeved on the outer periphery of the insert plate 1, the support plate 11 is located between the two protruding structures. The protruding structures abut against the side of the support plate 11 facing the opening of the guide groove of the slider 5 and the side facing away from the opening of the guide groove of the slider 5. The protruding structures and the support plate 11 form an interference fit. After the second baffle 3 is pushed close to the slider 5 by external force, the second baffle 3 and the insert plate 1 form a snap-fit fit under the action of the protruding structures clamping the support plate 11.
[0046] like Figure 5 and Figure 6 As shown, in one embodiment, to facilitate the installation of the slider 5 on the guide rail 6, the bottom plate 42 is provided with a guide groove 44 at the end away from the first baffle 2. The bottom surface of the guide groove 44 near the first baffle 2 is aligned with the end surface of the insert plate 1 away from the first baffle 2. The guide groove 44 is used to cooperate with the guide rail 6 that mates with the slider 5. When the side of the guide rail 6 abuts against the side wall of the guide groove 44 and the end surface of the guide rail 6 abuts against the bottom surface of the guide groove 44, the guide rail 6 and the guide groove of the slider 5 are aligned.
[0047] The top plate 41 is provided with a strip-shaped through groove 45. The length direction of the strip-shaped through groove 45 is parallel to the length direction of the first baffle 12. The strip-shaped through groove 45 is used by the external structure to push the slider 5 inside the outer shell 4 to the guide rail 6.
[0048] The process of installing slider 5 on guide rail 6 is as follows: First, take out the second baffle 3, bring the end of the outer shell 4 away from the first baffle 2 close to the guide rail 6, and make the end of the guide rail 6 located in the guide groove 44, and ensure that the side of the end of the guide rail 6 abuts against the side wall of the guide groove 44 and the end face of the guide rail 6 abuts against the bottom surface of the guide groove 44. At this time, the guide rail 6 and the guide groove of slider 5 are aligned, and the end face of the guide rail 6 and the end face of the insert plate 1 away from the first baffle 2 are connected. The insert plate 1 and the guide rail 6 are connected to form a continuous track for slider 5 to slide, keeping the length direction of the guide rail 6 in a vertical state, and the outer shell 4 above the guide rail 6, so that slider 5 can slide down to the guide rail 6 under the action of gravity. In other embodiments, it is not necessary to keep the length direction of the guide rail 6 vertical. In this case, the slider 5 needs to be moved by the strip groove 45 on the top plate 41 so that the slider 5 is close to the guide rail 6 and fitted onto the guide rail 6. After the slider 5 is fitted onto the guide rail 6, the outer shell 4 and the guide rail 6 can be separated. During the docking process, the guide rail 6 and the insert plate 1 dock together, which can avoid the situation where the ball bearing 55 falls off during the installation of the slider 5 on the guide rail 6.
[0049] The length of the strip groove 45 extends from one side of the first baffle 2 to the corresponding position of the guide groove 44. Moreover, the end of the strip groove 45 away from the first baffle 2 does not penetrate the end face of the top plate 41 away from the first baffle 2, ensuring the stability of the frame on the side of the outer shell 4 away from the first baffle 2, and ensuring that when the slider 5 and the outer shell 4 are engaged, the slider 5 can be aligned with the insert plate 1.
[0050] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
